ROLL FOR CIGAR-MACHINES.

SPECIFICATION forming part of Letters Patent No. 451,748, dated May 5, 1891.

Application filed November 25, 1839. Serial No. 331,551. (No model.)

To all whom it may concern.-

Be it known that we, RICHARD A. BRIGHT and WALTER A. PECK, citizens of the United States, residing at Providence, in the State of Rhode Island,have invented a new and useful Improvement in Rolls for Cigar-Machines, of which the following is a specification.

Our invention relates to that cl ass of rolls for cigar-machines which are made in several sections adapted to fit the longitudinal contour of the cigar-bunch; and it is the object of our lnvention to provide a sectional cigar-machine roll which may be made of increased diameter at its middle portion, and thus operate upon the inclosed cigar-bunch without tendency to twist the filler, and can also be externally supported and adjusted at any desired portion of its length; and our invention consists in means for externally supporting the joints of the sectionally-formed rolls for cigar-machines and for adjusting the same to make cigars of dilferent sizes and curvature; and it also consists in improved means for rotating the externally-supported roll-sections, as hereinafter fully set forth.

Figure 1 represents a side elevation of a sectionally-i'ormed flexible roll for cigar-machines provided with our improvement, the middle portion of the roll being broken away to show the method of supporting, adjusting, and rotating the roll-sections. Fig. 2 represents a partial section taken in the line 00 0c of Fig. 1. Fig. 3 represents a similar view showing a modification in the supportingbearing at the joint between the roll-sections. Fig. 4 represents a section taken in the line w :0 of Fig. 3. Fig. 5 is a sectional view showing the construction of a roll for cigar-machines made of rigid hollow sections, which are rotated by means of a spiralwire'coil forming a flexible shaft. Fig. 6 is a similar view showing a modification in the flexible driving-shaft. Fig. 7 is a detail View showing the universal coupling-joint of the flexible driving-shaft shown in Fig. 6. Fig. Sis a sectional view showing a modification in the construction of the roll-sections.

I11 the accompanying drawings, Figs. 1 and 3, A may represent a portion either of the rollsupporting head or the roll-supporting jaw of a cigar-machine, and B is a torwardly-extending arm which serves to support the outer end of the flexible roll R, which is formed of two tapering sections E and G, made of spirally-coiled wire. tated by means of the attached gear I, and is provided at its outer end with the bushing 0", which may be provided with a screw-thread adapted to enter the space between the convolutions of the cylindrical wire of which the roll-sectionisformed,thusholding thebushing firmly within the end of the roll-section; or the bushing may be held within the end of the spiral roll-section by means of solder. The bushing 9 is also provided with a screw-threaded recess 8, in which is secured the spiral wire 25, which is also secured in a recess 5 in the corresponding bushing r of the forward roll-section E. The spiral wire extends through the bearing a in the adjustable bracket D, the said bracket being provided with the guiding-arms w to, which fit into the guidingnotches w or of the edges of the supportingarm B. The adjusting-screw y turns loosely in the arm B and is threaded into the screwsocket z in the bracket, so that upon turning the screw y the bracket D can be adjusted, as desired, to change the curvature of the roll R, the spiral wire t serving to transmit the rotary movement of the roll-section G to the roll-section E through the bearing a of the bracket D.

In Fig. 3 the adjustable bracket D is shown provided with spherical cheeksmm, which fit within the corresponding concave recesses 11.

n in the bushings 1' r of the two roll-sections,

and in this case the cheeks 'm m will serve to form the joint-bearing for the roll-sections without pressing upon the connecting Wire spiral t, as in Fig. 1. The roll-section G is supported at its opposite ends and is also held in a properly-curved position by means of the bearing-arm J, which by means of a screw and slot may be adjustably attached to the arm B, and which bears against the upper side of the said roll at near its tuck-forming portion, and by adjusting the joint-holding bracket D either inwardly or outwardly the The roll-section G is ro-- size and shape of the cigar can be changed, as desired.

The adaptation of our improvement to rolls for cigar-machines formed of rigid roll-sections is shown in Figs. 5 and 6, in which A may represent a portion either of the rollsupporting head or the roll-supporting movable jaw of the cigar-machine, to which is attached the forwardly-exten ding arm B, which serves to support the bearing-brackets of the several roll-sections. The hollowed tapering end section 0, which serves to roll the head portion of the cigar-bunch, is provided with a central socket aand with countersunk ends b and c, and is heldin a properly-inclined position to fit the longitudinal contour of the head of the cigar-bunch by means of the conical center ,dat the inner side of the arm B and the conical annular bearing 6 at the outer side fof the supporting-bracket D, which bracket is made in wedge shape and provided at its inner side 9 with the cylindrical annular bearing h for the outer end dot the hollowed tapering roll'section E, and the bracket D is secured to the arm B by means of the screw j. The supporting-bracket F for the enlarged ends 7:; and Z of the hollowed tapering roll-section E and the frusto-conical rollsection G is secured to the arm B by means of the screwj and is made in wedge form and provided at its sides with the cylindrical annular bearings h for the said ends, and the said roll-sections E and G are bored out to receive the spirally-coiled flexible shaft H, which also passes through the annular bearings of the brackets D and F. The flexible shaft H is joined to the spirally-coiled flexible driving-shaft H by means of the screwcoupling 0, and upon the inner end of the shaft H is secured the driving-gear I, the said shaft being supported in a properlycurved position by means of the bearing-pin P, which is held in the head or movable jaw A, and the bearing-arm J, which is secured to the supporting-arm B by means of the screw q, and which bears against the upper side of the flexible shaft H. The roll-sections G, E, and G may be secured to the flexible shaft. H by means of the set-screws r or otherwise, so as to revolve with the said shaft, and the surface of the said roll-sections at the inner side 8 of the roll should conform to the longitudinal contour of the cigar-bunch and the diameters of the roll-sections at any specific point between the head and the tuckrolling portions can be made approximately proportional to the corresponding diameters of the cigar-bunch at the said points, so that the roll will revolve the said bunch without the twisting action of the ordinary hollowed cigar-machine roll of solid construction.

The roll shown in Fig. 6 is provided with a flexible driving-shaft H, formed in sections a a a CL, which are connected to each other by means of a universal joint I), a section of which is shown in Fig. '7, the forward end of the several shaft-sections being provided with an ear 0, into which is secured the crosspin d and is loosely held in the diametrical groove 6 of the opposite shaft-sectlon, pin (2 entering the elongated holes ff 1n the ears g g, which will allow for the proper angular movement of the joints.

Another modification is shown in Fig. 8 in which both the wire spiral and the flexible shaft are dispensed with and the roll-sect1ons are made adjustable at the joint, and in this case we provide the adjustable bracket D with the spherical cheeks m m, Wl'llOll fit into the corresponding concave recesses 72 n of the roll-sections and provide the roll-sections with the studs K K, which enter the bearing to of the bracket D and engage with each other by a universal joint, which may be formed by a square end upon one of the studs and a corresponding square socket upon the end of the other stud, so that upon the rotation of one of the roll-sections a corresponding rotary movement will be imparted to the other. The bracket D is made thinner than the width of the space between the ends of the rolls in order to allow for the required change in the angular position of the rollsections in their proper adjustment.

We do not claim in this specification the combination, with a flexible roll, of a bridge for holding said roll in position, as such combination is made the subject of a claim in our pending application, Serial No. 348,6?3. Neither do we claim, broadly, in this speclfication a flexible cigar-forming roll supported for revolution in a curved position, and having its form or contour capable of ad ustment to adapt it to form cigars of diiferent shapes or different diameters, as the same is made the subject of a claim in our pending application, Serial No. 268,395.
